The sentences were too lenient IMHO. You might be interested to know that a member of the public has now petitioned the Attorney General that the sentences were, indeed, too lenient. He now has to review those sentences and I believe he has to do that within 28 days. The judge, in his summing up, was clear that the maximum he could sentence them to was determined by the law regarding the minor age issue. He inferred that he would have sentenced them to longer terms if he could have done so.
It is also interesting to note that since the sentences were passed further information has been passed to the police regarding the other suspects who allegedly took part in the attack on Stephen Lawrence. This information appears to have come from people who were too scared to offer it until these two were in prison, that, if true, only goes further to cement the level of threat and intimidation that these people inflicted upon anyone they could to maintain their own freedom. They are guilty and they deserve to rot for what they did to Stephen Lawrence, his family and the community at large. They have had their taste of freedom, the Lawrence family will always be prisoners of their despicable actions.
